Date: Wed, 02 Jul 2025 18:01:04 +0000 [thread overview]
Message-ID: <bug-220307-208809@https.bugzilla.kernel.org/> (raw)
https://bugzilla.kernel.org/show_bug.cgi?id=220307
Bug ID: 220307
Summary: USB cannot submit urb disconnecting sound card
Product: Drivers
Version: 2.5
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P3
Component: USB
Assignee: drivers_usb@kernel-bugs.kernel.org
Reporter: targz@rambler.ru
Regression: No
Just got an error that looks like that in dmesg. Not sure what made it such,
just using sound card with Pipewire on 192000 Hz, 53 samples quantization. This
leads to about 0,275 ms delay while preparation of node to play sound takes
about 0,250 ms when VLC starts playing a video. Pw-top reports about 0,3 ms
delay in Busy field if that matters. With 64 samples there was no issues with
preparing the node to start playing and had no conflict with hardware using
standard Arch kernel 6.15-4-arch2-1. So seems this is a USB bug when sound card
drops off and gets up stopping playback of sound while video goes further.
